Comcast has launched its long-awaited (by some) 24-hour 3D channel, Xfinity 3D. This adds to Comcast's other 3D offerings like ESPN 3D, the 3D events channel, and the 3D on demand movies. The channel launched with broadcasts of a Kings of Leon concert and the NHL Heritage Classic 2011 hockey game.

You can expect 3D nature documentaries, animated features, concerts, sporting events, and performances, although the schedule doesn't look to include too many hit movies or concerts at the moment. That said, this could be similar to years ago when a few HD channels were first lit up with nature shows and soccer games, giving HDTV owners something to watch. What do you think? Will dedicated 3D channels spur sales of 3D television sets?

The benefits of Blu-ray are crystal clear: Video from traditional DVDs contains fewer than 350,000 pixels, while 1080p HD video packs more than two million, which translates to sublime, high-resolution detail. If you want to make the most of your 1080p HDTV, you should upgrade to a Blu-ray player.

And there's never been a better time to do it. The technology has matured, and the current crop of Blu-ray players offer stellar HD picture quality, fast disc-handling, and extras like integrated Wi-Fi, audio and video streaming, and in the case of Sony's Internet TV Blu-ray Player, Google TV, which brings Web search and other Internet features right to your HDTV.

These days you can find a very solid, well-rounded player for less than $200 if you do some smart online shopping. Still, there are a lot of choices out there. Here's what you need to consider when choosing the right Blu-ray player:

If you own a 3D HDTV and have been waiting for Avatar 3D to drop on Blu-ray, it looks like you’ll have to wait a bit longer than originally planned if you don’t own a Panasonic Viera model television. The long-awaited title is the first 3D Blu-ray movie that will get serious attention from home theater enthusiasts, and is seemingly a huge opportunity to sell consumers on the technology, so it’s pretty disappointing that Panasonic scored this timed exclusive that will keep Avatar off of the store shelves for a while. The movie will come bundled with select Viera 3D models, but if you already own one, there will be a way for you to get in on it as well. Look for it before the end of 2010.

When Nintendo announced the 3DS, they made sure to make the press aware that children should have the 3D effect disabled if they were going to use the handheld console. Manufacturers of 3D HDTV sets have also included warnings that stated that there is a possible health risk to certain viewers, and have provided guidance that children should be limited in their 3D exposure. Year ago, Sega was going to release a 3D virtual reality headset that was quickly and quietly shelved, despite being seen as the future of gaming 15 years ago. Now news has come out that all of these warnings are based on years of research cover ups, and the details are finally being brought out now that 3D entertainment is much more readily available than it was in years past.

In a nutshell, the problem is that children under 7 are still developing their vision, and the 3D effect actually forces you into strabismus, essentially giving yourself temporary lazy eye. Since children are still developing, you run a severe risk of having them end up with permanent strabismus (or, lazy eye.) This is the reason that so many manufacturers want to be overly cautious with the use of 3D as it pertains to children, and it’s also a good reason for parents to sit up and take notice as well. Now that 3D HDTVs are on the market, we’ve gone from having super rare opportunity to view 3D content, to a bunch of animated movies incorporating it (so, 2-6 hours per month, depending on how often you go to those,) to potentially having 3D on in your home on a constant basis.

A lot of higher-ups within the consumer electronics industry point to the fact that the data is 15 years old, and that they may be new factors since the technology has advanced. However, the fact remains that all content that shows a different image to each eye (which is all 3D) forces you into strabismus. More research is needed to find out if 3D HDTV is safe for children, as well as adults, especially for prolonged lengths of time.
